| Abstract: | Simulating interactions involving compressible fluids with potential shock waves and highly deformable structures demands the precise capture of flow dynamics and structural responses. This coupling must effectively manage substantial deformations while adapting to changes in the fluid domain's topology. This study focuses on the rhoSonicFsiFoam solver, developed using the open-source computational fluid dynamics (CFD) software, OpenFOAM. The computational approach addresses aeroelasticity, fluid compressibility and advanced coupling. Two tests were performed, with the first involving the beating of a thin plate in supersonic flow and the second featuring the interaction of a shock wave with a deformable plate. In the flutter test, simulation results intimately matched the theoretical Mach number of 2.2677, indicating a strong alignment between the numerical results of this present study ( M ∞ num ∈ 2.26 , 2.27 ) and theoretical expectations. Additionally, simulation results from the computational approach closely align with theoretical projections for plate fluttering and correlate well with experimental and numerical outcomes from the T80 shock tube. This project aims to unravel fluid–structure interaction by combining a robust solution method with the latest advancements in CFD. Leveraging this platform, the computational approach accurately captures aeroelastic phenomena, including shock waves and deformations during interactions with compressible fluid and deformable structures. Implications span aerospace, defense and energy sectors. In conclusion, this study underscores the pivotal role of advanced simulation techniques in comprehending intricate interactions involving compressible fluids and structures. [ABSTRACT FROM AUTHOR] |
